NOTEah. Using the piston ring installing tool, slidepower piston plug (96) over piston (99) until the ad-vance adjusting screw (112) enters threaded hole inplug.ai. Insert screwdriver into advance adjustingSC reW and turn out screw until approximately onehalf inch protrudes from plug. Do not turn pIug onpiston as piston ring damage may result.aj. Slide assembled piston and plug into advancebore at “C” side of advance housing and thread pluguntil the cam pin bore is aligned with pin bore ofcam.ak. Install advance pin (102)..—al . Place advance spring (108) into piston cavityand thread the spring side piston hole plug (111) intoadvance housing.am. Tighten both plugs and install adjusting screwnut (114) and seal (113).an. Turn the pump back to its original position (topupward) in the vise.ao. Install the metering valve (93) and shims (95)into its bore.Depress and rotate the valve severaltimes to insure freedom of movement. If valvesticks, lap it in carefully with clean oil. Never sandor polish off the special surface treatment provided.ap. Pull back on the governor linkage hook (45),stretching the spring just enough to connect the hookcorrectly to the fork on the governor arm (86).Position the opposite end over the pin on the meteringvalve arm (91 ). Check all of the governor parts againfor freedom of movement.aq. With end plate removed (59), assemble thespeed droop control rod assembly (79) throughthreaded hole from inside of pump housing.ar. Slide speed droop guide (75) with O-ringseal (77) assembled over end of rod (79) andthread into rear of housing.Do not overtighten;allow O. 010” clearance between guide (75) andpump housing face,The apparent looseness in the governorparts is normal.Lost motion is im-mediately taken up as soon as the pumprotates.aw. Assemble the throttle shaft assembly (26) andlever assembly (32) partially through its bore in thehousing. Slide the spacer bushing (38) and throttleshaft lever (40) over the throttle shaft so that theprojection on the throttle shaft lever bore engagesthe keyway on the shaft.Position the forked end ofthe throttle lever so that it straddles the guide stud.Apply a light coat of grease to the throttle and shut-off shaft seals (35, 3 6). Assemble the shut-offshaft assembly (24) from the opposite side with aslight rotary motion.So as not to damage the seal,firmly seat the two levers. Locate and seat the shut-off cam (25).ax. With the throttle lever in wide open position,check the clearance between the rear of the shut-offshaft (B) and the vertical tab (A) on the linkage hook.This clearance should be O. 250 inch.(See figure14-22)NOTEAdjustment of this clearance in the pumpis made by changing the effective lengthof linkage hook.ay. With adjusting screw (C) tight, apply a slightpressure to tab (A). At the same time rotate pumpone or two complete revolutions to assure that link-age is in full forward position. Loosen adjustingscrew (C) and slide linkage to maximum open length.Insert linkage gauge between vertical tab (A) andshut-off shaft (B) and slide linkage hook togetherfrom rear until face of tab is flush against gauge.Tighten adjusting screw (C). Check adjustment andreset if required.az. Check all governor parts for freedom of move-ment. Assemble a new seal (6) to cover (4), and in-stall cover on pump, tightening the three retainingscrews (1) securely.14-46. Solenoid Inspection and Repair.as. Insert clip (78) into hole at end of rod (79).—at. Assemble seal (74) to groove at end of guide(75)—and adjust speed droop cap assembly (73) overseal.au. Install end plate making certain locating pinenters slot in transfer pump liner. Assemble flat(61) and lock (62) washers four end plate screws (60)and tighten to 35 inch-pounds.av. Thread five full turns of spring (80) onto speeddroop rod assembly (79). Slip free end of spring(80) o er formed ends of governor arm (86) with thebent-in ends of the spring between the two tabs.a. Crank engine and check for 24 Vdc across sol-en~d leads on top of injection pump.b. If voltage exists, loosen an injector couplingan~check for full line of fuel. If fuel is not available,solenoid has failed.c. Remove the cover contact nuts (7, 8) andwas%ers (9, 10) and work the solenoid assembly outof the cover.Remove the shut-off spring (13) guide(14), and arm (15).d. Examine the solenoid visually for cracks andsw~ling in the encapsulating materiaI and looseness14-50
